The Sony FE 70-200mm f/2.8 GM OSS E-mount Lens has not yet been release, as it is a new item that was recently announced, and is not yet stated to begin shipping until July 29, 2016. As such, I have yet to see any lens testing from reputable testers to compare the optical quality of the two lenses. The newer Sony FE 70-200mm f/2.8 GM OSS E-mount Lens has 11 aperture blades for a more rounded aperture and bokeh (the A-mount lens used 9 blades), and also has more optical elements designed for more correction from aberration and to focus all light at a single point to increase sharpness, and also has a shorter minimum focus distance. The above are the comparisons from the lens' specifications released by Sony. Comparing the MTF chart, the newer Sony FE 70-200mm f/2.8 GM OSS E-mount Lens seems slightly sharper, especially when viewing the corner/edge performance. However, for a comparison in real-world testing, you would have to wait until the lens is released and available for testing.I will add one point; if you are using both A-mount and E-mount cameras, and you only want to have to purchase one lens, then the Sony 70-200mm F2.8 G SSM II would be recommended. While both are good lenses, you may use an adapter to use the A-mount lens on the smaller E-mount, but there is no adapter to use the smaller E-mount lens on the larger A-mount.

Both options would provide excellent image quality. However, having the FE 70-200mm f/2.8 GM OSS lens with the FE 2X Teleconverter allows you to shorten the range as needed by removing the teleconverter. With the FE 100-400mm lens, you’re stuck within a longer range unless you back up.

Yes, this is possible. Gearing can be attached to the Zoom and Focus Rings to enable control via a Follow Focus system.

Both. And everywhere in between.

Unfortunately, the above is not a question; there is no information listed besides Sony 24-70, so there is no way to respond to the above. You would either have to re-phrase your inquiry as a complete question, or send your inquiry concerning the lens to prophoto@bhphotovideo.com.

The optics are glass and the lens is metal.

Yes, it is.
